Jamis DAKAR BAM Owner's Manual - 4Fswjdf

The Presta valve (fig. 18) has a narrower diameter and is only found on bicycle tires. To inflate a Presta valve tube 

using a Presta headed bicycle pump, remove the valve cap; unscrew (counterclockwise) the valve stem lock nut; and 

push down on the valve stem to free it up. Then push the pump head on to the valve head, and inflate. To inflate a 

Presta valve with a Schraeder pump fitting, you’ll need a Presta adapter (available at your bike shop) which screws 

on to the valve stem once you’ve freed up the valve. The adapter fits into the Schraeder pump fitting.  Close the 

valve after inflation. To let air out of a Presta valve, open up the valve stem lock nut and depress the valve stem.

WARNING

: Patching a tube is an emergency repair. If you do not apply the patch correctly or apply 

several patches, the tube can fail, resulting in possible tube failure, which could cause you to lose control 

and fall. Replace a patched tube as soon as possible.

WARNING

:  Technological advances have made bicycles and bicycle components more complex, and the pace of innovation is increasing. It 

is impossible for this manual to provide all the information required to properly repair and/or maintain your bicycle. In order to help minimize the 

chances of an accident and possible injury, it is critical that you have any repair or maintenance which is not specifically described in this manual 

performed by your dealer. Equally important is that your individual maintenance requirements will be determined by everything from your riding 

style to geographic location. Consult your dealer for help in determining your maintenance requirements.

!

WARNING

:  Many bicycle service and repair tasks require special knowledge and tools. Do not begin any adjustments or service on your 

bicycle until you have learned from your dealer how to properly complete them. Improper adjustment or service may result in damage to the bicycle 

or in an accident which can cause serious injury or death.

If you want to learn to do major service and repair work on your bike, you have three options:

1

.  Ask your dealer for copies of the manufacturer’s installation and service instructions for the components on your bike, or contact the component manufac-

turer.

2

.  Ask your dealer to recommend a book on bicycle repair.

3

.  Ask your dealer about the availability of bicycle repair courses in your area.
